This is my first guide, so bear with me if it's not formatted beautifully like others!

I will go through talent choices and changes in gameplay depending on the level you reach while you complete this build.

Talent of choice:

The first talent choice should go to this talent as it will help both pushing your lane and keep some distance from walls/structures and, later on in the game, hit both towers or tower and fortress, once we get the talent.

Other talents..

The way i see it, this is more of a talent for team fights and works better in sinergy with other talents.

This would be a strong second choice for the siege build, simply because by doing more damage to minions and mercenaries, you get more stacks. This will make it difficult to hit multiple targets with the talent though!

Because of , this talent is useless. You will be able to solo towers and fortresses without having them shoot a single ammo.

Talent of choice:

This gives you a way of recharging stacks immediately while doing some damage and, if required, teleport to another location. Paired with the talent gives 10 stacks in a few seconds!

Other talents..

It might sound useful but at the end you will be able to shoot enough that you won't require this.

This talent is more useful when you are pushing a lane rather than in siege mode, in my opinion. It also would make more sense if there was a mana cost on shooting .

Useless on buildings... enough said!

Talent of choice:

Once you get this talent, you can change your playstile and start shooting every second. As you get the timing right, you will be able to activate this, wait for the auto attack to happen, fire again and so on. You can start positioning yourself close to one tower and target the other tower as well, allowing you to stunlock 2 towers at once already,or 2 mercenaries! All of this while doing increased damage.

Other talents..

This works better if you are trying to push the lane and kill minions/mercenaries.

This can become your choice if you don't have an healer in team. Considering how you will stun towers and fortresses, this might still become less useful as you will have less incoming damage not only on yourself but also on the minions nearby you.

Only if you plan on getting alot of help from mercenaries while besieging the enemy. The constant bonus damage from triggered by might provide still a better choice though.

With this build you don't really need to sneak around, as you will be knocking at the enemy's doors!

Talent of choice:

This talent can provide alot of instant damage to both structures you are attacking or enemy minions/heroes.

Other talents..

As it stands, this power feels too weak compared to the other hero ability.

Talent of choice:

This allows you to stunlock an extra target, be it a minion, mercenary or tower. Positioning yourself closer to the first 2 targets while shooting at the 3rd one with auto attacks, while timing the to avoid anything to fire ammo at you or your minions.

Other talents..

This talent doesn't give any benefit on structures.

This can be situational, when you want to hit and run on maps that already provide meanings to destroy walls and towers, but you might not want to use this build on those maps at all!

Another talent that becomes useless as soon as you manage to stunlock towers and fortresses.

Talent of choice:

Combined with gives alot of stacks of to use to start your siege to the enemy buildings! It can also be useful to escape tricky situations, as well as provide double the aoe damage.

Other talents..

This talent doesn't give any benefit on structures, but if you feel like you are getting enough stacks of it might be a strong second choice, to allow you to wipe out incoming minions faster.

Another mobility talent that could be taken in consideration but doesn't provide any damage increase compared to .

No benefits on buildings, something to consider only if you are alone against 2 or more enemy heroes too often.

Talent of choice:

If all goes well, at this point there should be a limited amount of structures left and you are trying to push the core. Increasing damage on this can help control your opponents while doing more damage.

Other talents..

If for any reason you picked , you might want to pick this to convert enemy mercenaries to your side.

Better choice if you took and now you want more damage output to clear enemy minions/mercenaries.

In my opinion this is redundant, especially if you choose , altough this is mana free and provides another mean of escape.

The second build is more focused on killing enemy heroes.
If i want to switch to a minion killing build, i swap the tier 1 talent for extra range and tier 5 for extra shots.

This build uses clever positioning and timing to allow stunning the enemies towers and fortresses. If you manage to pull this out, your waves of minions will keep pushing while the enemy structures will be destroyed without having chance to fire their ammo.

I will be honest saying I only tested this build in Cooperative so far, which means I don't have a clear idea of which heroes are stronger against this build, altough anyone might feel discouraged when they see their buildings are not helping defend!
The AI in coop, infact, usually responds by pulling back, when 1 on 1.

Use and to stun the waves of enemy minions and your lane will push all the way to the enemy core!

both are more than welcome! I'm not assuming this build is perfect at all! I simply thought I would share it with everyone and see what you guys thought!
